the c/r on flop looked weak (draws, bluffs), so I called.
on the turn, is it better to raise or call? if I raise to 15-18 I have to shove any river? Maybe dont shove if river is spade?
as played, could I bet more to get value from Qx hands on river?
thank you

yeah, his hand is quite often Qx that he would likely not really like fold too often, so I´d also just call turn and raise river if I improve my hand
To get value from Qx, I think he would also call 15$ bet so you can bet river a little bigger
